HANGER FOR SHAFTING.

SPECIFICATION forming part of Letters Patent No. 225,757, dated March 23, 1880.

Application filed January 29, 1880 To all whom it may concern:

Be it known that 1, AUGUST LOEHNER, of the city of St. Louis and State of Missouri, haveinvented certain Improvements in Shaft- Hangers, of which the following is a description and specification.

My invention relates to that class of shafthangers designed to effect the adjustment of shafting to true lines of position, which I accomplish by new compound devices therefor.

In said invention two principal movements of its fundamental parts afford correct vertical or horizontal adjustment to shafts hung thereon, while for any adjustment to other than right angles the devices therefor secure accuracy, fixity in place, and facility of application, in contradistinction to ordinary shaft-hangers, which attach directlyto the snpportin g-timbers. My shaft-hanger has a strong bed-plate, hav ing thereon raised retaining-flanges or parallel turned-in beveled edges, which, together with the bottom of said plate, if smoothly and truly planed, form a close-fitting seat for the movement therein, either inwardly or outwardly, of a ribbed web-plate, to which the hanger-frame attaches, by which construction the said bedplate, if permanently bolted with its back to the fixed timbers therefor, permits the intended range ofmovement of the said web-plate, which carries thereon the said hanger, with any shaft therein, to adjustment in either of its directions of movement, a strong set screw holding it thereat.

In the accompanying drawings,Figure 1 is a perspective view of my hanger constructed according to said invention and attached to the vertical timber by the bed-plate. Fig. 2 shows, part in perspective and part in section, the arrangement of the same as an overhead hanger. Fig. 3 shows how other than right-angled positions are given to the head which supports the shaft. Fig. 4 shows the same in a diverse position to the foregoing.

On the rib B of the web-plate A are formed the parts which constitute the hange r-viz., the stud 0, from the foot of which starts the truss-brace b, which eonjointly support the right-angled boxframe K, through whose longitudinal. center passes the cylinder-headed screw f, which its pointed center 1" holds in working position at one end, while the burr a,

which is securely riveted to the said screw, forms a check-shoulder, which bears against the opposite end of the said box-frame K.

The round nut-post D has at one end the squared part d, which is formed to act as a carrier-nut, through which the said screw passes and causes the said nut-post to travel, and carry, as moved,the truncated postF, which said post is established upon the socket-sleeve I, which, to possess the power to rotate, is placed on the axle E, a reduced portion of the said nut-post T D, and either tightly or loosely held thereto, as a nut and washer, 0, may be made to operate therefor. On the said socket-sleeve is formed the truncated box supporter F, which has bored in it the socket F,'into which enters the reduced end of the said box-supporter, a recess, i being sunk thereon, into which the set-screw 0 may be screwed, and serve to secure the said box-supporter to its truncated base, and also permit it to rotate on its shoulder h whenever so required during the shafts alignment. On the neck F" of the said box-supporter is formed the box 1 into which the shaft S is placed, and held down by the cap I, which is attached by the hinging i to the said box 1 and the hinged bolt j, which turns up into the slot formed between the ears Z, the requisite additional tightness being given by turning the nut on said bolt j. The bed-plate A admits the beveled edges of the said web-plate A between and under the overlapping parallel flanges o o, and when in position is held thereto firmly by the bolts 1), through bosses k, the said web-plate being slid to adjustment as required, and then held immovably to said bedplate by a strong set-screw.

The carrier-screw f is operated by a bar through its cylindrical head gto the movement, as requisite, of the said carrier-nut d, and therebyeifects a most essential adjustment.

I11 the setting up of my shaft'hanger it is most important that the timbers to which a line of shafting is to be attached should have a true leveling for the bed-plates, it not being necessary that protruding timbers be hewed back to line, nor do receding timbers require to be pieced out. When the bed-plates are properly bedded and bolted the adjustment in any direction of the shafting which may be hung thereto is only a matter of judgment as to which adjusting device the true alignment should come through. Intervening walls or partitions are not with me the serious impediments to true'lining, almost unavoidable with all other arrangements within my knowledge.

I do not claim as my invention the application to shaft-hangers of variable joints.

What I claim as my invention is 1. In a shaft-hanger the bed-plate A with flanges 0, and the adjustable web-plate A, provided with the bracket B O b, and box-arm K, in which is placed lengthwise a screw, f, which passes through, and on which moves the nutpost, to which is secured a device for holding the'shaft, substantially as set forth.

2. In a shaft-hanger, the box'arm having the carrier-screw with burr u, said screw passing through the nut d of the post I), provided with the axle E on which the shaft-holding device may turn, as herein set forth.

3. The shaft-holdin g box I with hinged cap I, and neck F, provided with shoulder 71/ and recess 6 and the truncated post having socket F and set-screw e, andprovided with sleeve I to receive the axle E, as and for the purposes set forth.

4. In a shaft-hanger, the bed-plate A, having the web-plate A to move thereon, the bracket provided with the box-arm, with the carrier-screw f passing through the nut d of the post D, provided with the axle E, which forms the axis of the post I, the box 1 having a shouldered neck resting in a socket, F, of post F, the parts being constructed and arranged substantially as set forth.

In testimony that I claim the foregoing as my own invention I affix my signature in presence of two witnesses.

AUGUST LOEHNER.
